Il Claims.

My present invention relates to the jewelry art, and has particularreference to bracelet constructions.

It is the principal object of my invention to provide an improvedextensible bracelet for use with wrist watches, ornaments, and the like.It is a further object of my invention to provide a simple, easilyoperated arrangement for setting the length of the bracelet to t thewrist of the wearer.

It is an additional object of my invention to provide an improved endconnection arrangement for securing the bracelet ends to a wrist watchor the like.

Another object of my invention is to utilize parts made of sheet metaland the like which are strong and sturdy and which can be manufacturedat a relatively low cost.

With the above and other objects and advantageous features in View, myinvention consists.

, of a novel arrangement of parts more fully dis,-

closed in the detailed description following, in conjunction with theaccompanying drawing, and more specically defined in the claims appendedthereto.

In the drawing:

Fig. 1 is a plan view of the assembled bracelet construction;

Fig. 2 is an enlarged section on the line 2 2 of Fig. 7; e

Fig. 3 is a section similar to Fig. 2, the parts being separated;

Fig. 4 is a perspective of the adjustable base;

Fig. 5 is a perspective of the cooperating catch;

Fig. 6 is a plan View of a construction suitable for leather bracelets,the parts being separate;

Fig. 7 is a similar view, the parts being assembled;

Fig. 8 is a side elevation of Fig.` 7;

Fig. 9 isa perspective view of the novel end connection for use with anarrow bracelet of the type shown in Fig. 1; v l

Fig. 10 is a view similar to Fig. 9, the parts being in open position; p

Fig. 11 is a perspective View of the end connection base; and

Fig. 12 is a perspective view of the end connection lock ring.

Referring to the drawing, the novel bracelet construction I0 includes astrap II and a cooperating strap l2, secured to a watch or the like bynovel end connections I3. The straps are preferably made of exiblemetal, and particularly for narrow bracelets, the strap i2 having aslidably adjustable base Ifl, and the strap I I a cooperating hook catchi5, the end of the strap i2 having II.

The base lf2, see Fig. 4, includes a frame I l, preferably of sheetmetal, having a atlower plate i8 and side edge plates I9 of preferablyrounded shape, a clamp plate 20 of sheet metal having integral side ears2l which are seated in corresponding openings 22 in the edge plates i9so as to have a limited motion to and from the lower plate, a pivot pin23 being seated at its ends in the edge plates to serve as a pivotalsupport for a cam plate 2t, which is preferably curved as illustrated,and has a cam 25 for engaging the clamp plate to force it towards thelower plate to lock the strap therebetween. The cam plate is cut away asillustrated in Fig. 4, where-v by the hook 2t of the catch Iii maylockingly engage the pivot pin 23. As best shown in Figs. 2 and 3, thecatch l5 has a base portion 2'! with side edges 2&3, a pivot pin 29beingmounted between the side edges 23 at one end to receive a loop or.similar connection Sil of the strap II, and a second pivot pin 3i beingmounted between the side edges 28 at the other end to pvotally a loop itslidably embracing the strap mount the endv 32 of a member 33 which hasa closure element SlIhingedthereto, a spring 35 being mountedon thepivot pin 3| to normally urge the member i'away from the base portion2l, whereby the closure element which passes through a slot in the baseportion 2l, may move upwardly, see Fig. 2, to close the end of the hook2S. The end of the closure element is formed to be engaged by the iingernail to be moved against the action of the spring 35 for opening thehook 25 to permit removal of the hook from the'pin 23; a secondarylinger lever may be used, if desired, hinged to the element 34.

The above described arrangement may be readily adapted for Widerbracelets, such as for example illustrated in Figs. 6 to 8, which arepreferably made of leather. The parts are generally similar to the partsshown in Figs. l to 5, and are indicated by similar reference charactershaving the letter a as part thereof.

' It is preferred to use a novel form ofend connection with thedescribed type of bracelet, see Figs. 1, and 9 to l2 inclusive. The endconnection I3 includes a circular frame 36 of channel cross-section,having an opening or slot 3l at one end thereof and a detent 38 at theopposite end. A ring 39 is seated in the frame, having a lock portion40, and two spaced teeth or projections 4I opposite thereto, adepression 42 being positioned between the teeth 4I and diametricallyopposite the lock portion 40, for cooperating with the detent 38. Anopening or slot 43 is positioned intermediate one tooth 4I and the lockportion 40, to permit passage of a watch bail such as indicated at 44,Fig. 1.

With the parts assembled as shown in Fig. l0, the end 45 of the strap ispositioned between the teeth 4I, and the slot 43 permits passage of thebail 44 to engage the end connection. The end 45 is now turned, and thering 3B also turns, because of the teeth 4|, until the lock portion 40bridges the opening 31 to lock the strap end and the watch bailtogether, the depression 42 cooperating with the detent 38 to preventaccidental turning of the ring 39 in its frame.

While I have described specic constructional embodiments of myinvention, it is obvious that changes in the shape and size of theparts, in the relative arrangement of the parts, and in the materialsused may be made to suit diierent designs for bracelets, withoutdeparting from the spirit and the scope of the invention as defined inthe appended claims.

I claim:

l. In a bracelet construction, two straps, one strap having a loop atone end and the other strap extending through said loop, the first straphaving a slidable base comprising a lower plate and a movable platerespectively positioned on opposite sides of said strap, said lowerplate having edge plates, a pivot pin having its ends secured to saidedge plates, and a cam element hingedly mounted on said pivot pin andmovable to press said movable plate into gripping engagement with saidstrap, and the second strap having a member at one end, said memberhaving a fixed portion engageable with said pivot pin and aspring-pressed lock adapted to be normally positioned at the end of saidhook to releasably lock said hook in engagement with said pin.

2. In a bracelet construction, two straps, one

strap having a loop at one end and the other strap extending throughsaid loop, the iirst strap having a slidable base comprising a lowerplate and a movable plate respectively positioned on opposite sides ofsaid strap, said lower plate having edge plates, a pivot pin having itsends secured to said edge plates, and a cam element hingedly mounted onsaid pivot pin and movable to press said movable plate into grippingengagement with said strap, and the second strap having a member at oneend, said member having a hook engageable with said pivot pin and aspring-pressed lock member normally positioned adjacent the end of saidhook to prevent disengagement of said hook from said pivot pin andmanually movable to permit disengagement therefrom.
